Realize rapid measurement of water quality indicators such as residual chlorine (free chlorine), total chlorine, ammonia nitrogen, chemical oxygen demand (COD), total nitrogen (N), total phosphorus (P), phosphate (acid hydrolyzed phosphorus, active phosphorus), nitrate (nitrogen), etc.

High performance COD multi parameter analyzer, capable of quickly measuring important water quality indicators such as residual chlorine [free chlorine], total chlorine, ammonia nitrogen, chemical oxygen demand COD, total nitrogen N, total phosphorus P, phosphate [acid hydrolyzed phosphorus, active phosphorus], nitrate [nitrogen], using corresponding measuring reagents. Through the barcode on the reagent, it can automatically identify the required measurement items, parameters, and measurement range in the measurement items, without the need to manually pre-set measurement items or parameters through the menu. It has diversified measurement modes and barcode recognition function, and uses dedicated barcodes to prevent reagent confusion or incorrect measurement.
Fully embodies Hanna's people-oriented design philosophy; The advanced interactive user menu system and on-screen operation guide function enable users to gradually and quickly complete various operations under prompts, providing assistance in various stages of measurement and analysis
The multi parameter photometer adopts a carefully designed optical system, using LED, narrowband interference filter, focusing lens, and silicon photodetector and reference detector for absorbance measurement to maintain a consistent light source, ensuring accurate and reproducible photometric readings every time.

Large capacity data storage, with 200 sets of large capacity data storage functions, can store data including parameters, measurement results, sample codes, batch numbers, instrument IDs, dates, and times. It can be connected to a computer through a USB interface, and HI92000 software can be purchased to provide a systematic data management platform.
